To aZZ wlwmif may concern:

Be it known that lfLAY'roN B. VVnAvnn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have made a certain new and useful Invention in Machines for Stamping Sheet-Metal Shrouds for Automobile-Bodies, of which the following is a specification.

This invention lrelates to machines for stamping sheet metal shrouds for automo bile bodies. y

The object of the invention vis to provide a machine of simple struct-ure, and which is efficient in operation, for stamping the shrouds for automobile bodies out of sheet metal and at one operation.

A further object of the invention is to provide a machine for stamping out sheet metal 'shroucls for automobilebodies in one operation, and wherein the fianges around the doorway at the end of the shroud and at the bottom of the shroud and for the door bumper blocks are all made in one operation.

The invention consists substantially in the construction, combination, location, and relative arrangement of-parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

. Referring to the accompanying drawingsz- Figure 'l is a view in top plan of the frame work and die portion of a machine embodying the principles of my invention.

Fig. 2 is a view' partly in front elevation, and partly in vertical horizontal section on the line 2, 2, Fig. l, looking in the direction of the arrows.

F ig. 3 is a broken detail view on a somewhat enlarged scale in vertical section on the plane of line 2, Q, Fig. l.

Fig. 4 is a vicw in vertical transverse section on the line l, Fig. l, looking in the direction of the arrows.

Figs. 5 and 6 are views in front elevation and side view respectively, parts broken off and parts broken out, of a shroud stamping produced in a machine embodying my invention. y

Fig. 7 are details in front lelevation and side views respectively showing the stamped or pressed stamping in sets for the door bumper blocks.

the employment of various stamping machines, and is therefore not only slow but is also expensive. lt is among the special purposes of my present invention to provide a machine which completes the cowl stamping in one operation with the necessary shape or conformation, flanges, and seats formed therein, thus greatly expediting the manufacture of shrouds and materially ree ducing the cost of manufacture thereof. In carrying out my invention I provide die blocks which are capable of being forced apart or away from each other in opposite directions and over which the sheet steel blank is applied and cooperating with the side or die surfaces of said blocks. employ die members througl'i the oi'ieration of which the blank is pressed into the required form or shape/.the edge flanges are formed thereon, and the necessary seats or recesses provided, thus producing a completed article at one operation of a die press.

Any suitable construction of framework may be employed. ln the construction shown is a base plate 8, upon which side standards 9 are erected at the ends Aof said base plate. said side standards being suitably braced together bv tic rods 10. Mount ed within this framework are the die blocks ll. which are yicldingly drawn toward each other. as for example. bv means of the springs l2. but which die .blocks are capable of being spread apart or separated from each other. A vertically movable plunger 13 carried by a ram member lll, which latter is ypow r actuated. serves to effect the forcin apart of the die blocks 1l. and to this en said plunger is provided with the inclined surface 15 designed to cooperate with correspondingly inclined surfaces 16 on the juxtaposed faces of the sides of the die blocks 1l. 0n its side face or surface edge die block il is provided with a surface 17 upon or'against which theY sheet steel blank is ap plied and which is shaped to conform to the contour and outline of the completed stamping. This die face .or surface of the die completed stamping. Coperating with the lower portion of the side surface of the die bleek 11 andparticularlv with the shoulder 18 thereof to form the flange 20 at the lower edge ofthe stamping is a die member 21. This mei'nber is secured to a movable member 22 having an inclined surface 23 with which cooperates a similarlv inclined snrface Q4 on plungers 25 carried bv a power actuated ram 26. The member 22 is yieldinglv held in retracted position awav from the juxtaposed surface of the die block 11. This ma;7 be accomplished in any suitable or convenient manner. ment is shown wherein a rock shaft 27 is journaled at each end of the base plate 8. each rock'shaft carrying` an arm 28 upon which is mounted a counterweight Q9. The tension of the counterweights 29 are applied to the members Z2 through link connections 30 respectively disposed at the ends of the member 22. Disposed between the inner face of each member Q2 and the opposed side surface 17 of the die block 11. is a tloatcr member 31 which is held and guided by studssBQ and supplied with bolts 33 respectivelv engaging said floater and the member 02. lVhen the members 2Q are forced towardv the die face or surface of the die blocks 11 the floater 31 is likewise forced toward the same surface. Carried bv the upper surface of the {loater 31 is a die member 34 which copcrates with the member 19 to form the seat or recess 35 in the edge of the blank. The member 34 is adjustablv mounted upon thefloater 31, as for example. bv means of a bolt 36 operated throuefh an elongated slot 37 in the die member A face plate 38 bolted to the inner face of the member??` and extending abover the top of the fioater 31 engages the outer end of the die member 34 to ati'or'd an efticient backingl therefor.

The blank when applied 4around or upon the die blocks 11 mav be retained in place thereon in anv suitable or convenient manner, For this purpose a clamp arm 39 is emploved. This clamp arm is carried by a rocking support' 40 which is hinged upon a horizontal axis extending lengthwise of the machine at the front side thereof so that said clamp arm mav be swungforwardlv out of the wav to release the clamped blank or rearwardly into clamping relation to retain A simple arrangethe blank in position. When swung into clamping position the end 41 of the clamp arm is detachablv anchored in place by means of a wedge block 4Q, or otherwise, as mav be desired.

Having now set forth the objects and nature of mv invention. and a construction embodving the principles thereof.v what I claimy l as new and useful and of mv own invention, and desire to secure b v Letters Patent, im;
